The Ancient World, 9/E has been completely re-designed with a new, attractive full-color layout, including an entirely new set of maps. The book has been updated to reflect the latest research and findings since the last edition, and includes new information on the economy (from landscape archaeology, shipwrecks, and ice cores), the emergence and nature of the city-state (from, among other sources, the Copenhagen Polis Centre), and the new appreciation of the interaction of culture and religion, and of polytheism and monotheism.
